Has anyone tried the powermat for droid X?

I was at work the other day, and me and my friend decided to see what the powermat looked like on our dx's so we took an opened powermat and I tried it on my phone. For some reason, the powermat (basically just replaces the battery cover) did not fit at all, not even with a stock battery. It was so bad that I was scared to push any more fearing I would break the phone. I was wondering if anyone else has experienced this, seeing as it could be a huge problem with powermat sales.
